Water quality - Examination and determination of colour (ISO 7887:1994)

Water quality - Examination and determination of colour (ISO 7887:1994)

Cancels and replaces the first edition (1985). Specifies three methods for the examination of colour: a method for the examination of apparent colour by visually observing a water sample in a bottle; a method for the determination of the true colour of a water sample using optical apparatus; a method for the determination of the colour by visual comparison with hexachloroplatinate standard solutions. Under certain circumstances, strongly coloured water samples need to be diluted before examination or determination.

Damit wird nur eine vorläufige Information erhalten, beispielsweise bei Untersuchungen vor Ort. DasErgebnis kann nur als "scheinbare Färbung" angegeben werden. Hauptabschnitt 3 beschreibt ein Verfahren zur Bestimmung der Färbung einer Wasserprobe mit Hilfeeines optischen Gerätes. Das Verfahren ist auf Roh- und Trinkwasser und auf schwach gefärbtes Industrieabwasser anwendbar. Störungen siehe Abschnitt 3.3.

Qualité de l'eau - Examen et détermination de la couleur (ISO 7887:1994)

La présente Norme internationale prescrit trois méthodes d'examen de la couleur : La section 2 prescrit une méthode d'examen de la couleur apparente par observation visuelle d'un échantillon d'eau dans une bouteille. Cela donne une première indication, par exemple sur le terrain. Seule la couleur apparente peut être indiquée. La section 3 prescrit une méthode de détermination de la couleur vraie d'un échantillon d'eau au moyen d'un appareillage d'optique, et peut être appliquée aux eaux brutes et potables, et aux eaux industrielles faiblement colorées. Pour les interférences, voir 3.3. La section 4 prescrit une méthode de détermination de la couleur par comparaison visuelle avec des solutions étalons d'hexachloroplatinate et peut être appliquée aux eaux brutes et potables. Pour les interférences, voir 4.2. Dans certaines circonstances, des échantillons d'eaux fortement colorés nécessitent d'être dilués avant examen ou détermination. Dans le rapport d'essai, il est absolument nécessaire de mentionner la méthode utilisée.

EN ISO 10634:2018(Main)
Water quality - Preparation and treatment of poorly water-soluble organic compounds for the subsequent evaluation of their biodegradability in an aqueous medium (ISO 10634: 2018)
SIST EN ISO 10634:2019

This document specifies techniques for preparing poorly water-soluble organic compounds (i.e. liquid and solid compounds) with a solubility in water of less than approximately 100 mg/l and introducing them into test vessels for a subsequent biodegradability test in an aqueous medium using standard methods.
The subsequent tests on biodegradability are primarily methods using the analysis of the released carbon dioxide described in ISO 9439 and the determination of the oxygen described in ISO 9408 and following the usual precautions for ISO 10707. Thus, one can notice that the methods measuring the removal of dissolved organic carbon (DOC) are not appropriate.
This document does not specify the biodegradation test methods. It is restricted to describing techniques for introducing the test compounds into the test medium and to keeping them in a dispersed state[4]. These techniques are implemented while observing the experimental conditions described in the standardized methods for evaluating biodegradability. ISO 9439, based on CO2 evolution, is not suitable for testing volatile compounds.
Some of the preparation methods described in this document might not be accepted by regulators for making conclusions on the ready biodegradability of tested compounds.
Examples of biodegradability curves are given in Annex A.

Water quality - Enumeration of Escherichia coli and coliform bacteria - Part 1: Membrane filtration method for waters with low bacterial background flora (ISO 9308-1:2014)
SIST EN ISO 9308-1:2014

ISO 9308-1:2014 specifies a method for the enumeration of Escherichia coli (E. coli) and coliform bacteria. The method is based on membrane filtration, subsequent culture on a chromogenic coliform agar medium, and calculation of the number of target organisms in the sample. Due to the low selectivity of the differential agar medium, background growth can interfere with the reliable enumeration of E. coli and coliform bacteria, for example, in surface waters or shallow well waters. This method is not suitable for these types of water.
ISO 9308-1:2014 is especially suitable for waters with low bacterial numbers that will cause less than 100 total colonies on chromogenic coliform agar (CCA). These may be drinking water, disinfected pool water, or finished water from drinking water treatment plants.
Some strains of E. coli which are β-D-glucuronidase negative, such as Escherichia coli O157, will not be detected as E. coli. As they are β-D-galactosidase positive, they will appear as coliform bacteria on this chromogenic agar.

Water quality - Evaluation of the "ready", "ultimate" aerobic biodegradability of organic compounds in an aqueous medium - Method by analysis of dissolved organic carbon (DOC) (ISO 7827:2010)
SIST EN ISO 7827:2013

ISO 7827:2010 specifies a method for the evaluation of the “ready” and “ultimate” biodegradability of organic compounds at a given range of concentrations by aerobic microorganisms. In this context, ISO 7827:2010 also gives specific definitions for the terms “ready” and “ultimate”.
The method applies to organic compounds which are: a) soluble at the concentration used under the conditions of the test [dissolved organic carbon (DOC) concentrations of 10 mg/l to 40 mg/l]; b) non‑volatile or having a negligible vapour pressure under the conditions of the test; c) not significantly adsorbable on glass and activated sludge; d) not inhibitory to the test microorganisms at the concentration chosen for the test.
The method is not suitable for waste waters, as they usually contain significant amounts of water‑insoluble organic carbon, which is not included in DOC measurements.

EN ISO 5814:2012(Main)
Water quality - Determination of dissolved oxygen - Electrochemical probe method (ISO 5814:2012)
SIST EN ISO 5814:2013

ISO 5814:2012 specifies an electrochemical method for the determination of dissolved oxygen in water by means of an electrochemical cell which is isolated from the sample by a gas permeable membrane.
Measurement can be made either as a concentration of oxygen in milligrams per litre, percentage saturation (% dissolved oxygen) or both. The method measures oxygen in water corresponding to 1 % to 100 % saturation. However, most instruments permit measurement of values higher than 100 %, i.e. supersaturation.
The method measures oxygen in water with a saturation higher than 100 %, when special arrangements to prevent the outgassing of oxygen during the handling and measurement of the sample are made.
The method is suitable for measurements made in the field and for continuous monitoring of dissolved oxygen, as well as measurements made in the laboratory. It is the preferred method for highly coloured and turbid waters, and also for analysis of waters not suitable for the Winkler titration method because of iron- and iodine-fixing substances, which can interfere in the iodometric method specified in ISO 5813.
The method is suitable for drinking waters, natural waters, waste waters, and saline waters. If used for saline waters, such as sea or estuarine waters, a correction for salinity is essential.

Water quality - Examination and determination of colour (ISO 7887:2011)
SIST EN ISO 7887:2012

ISO 7887:2011 specifies four different methods, designated A to D, for the examination of colour.
The previously most employed method for assessment of water colour in water treatment plants, limnological surveys, etc. was based on the hexachloroplatinate scale. Methods C and D are harmonized with this traditional procedure.
Method A involves examination of apparent colour by visually observing a water sample in a bottle. This gives only preliminary information, for example for use in field work. Only the apparent colour can be reported.
Method B involves determination of the true colour of a water sample using optical apparatus and is applicable to raw and potable water and to industrial water of low colour. A subclause on interferences is included.
Method C involves determination of the true colour of a water sample using optical apparatus for comparison with hexachloroplatinate concentration at wavelength, λ = 410 nm. A subclause on interferences is included.
Method D involves determination of colour by visual comparison with hexachloroplatinate standard solutions and can be applied to raw and drinking water. A subclause on interferences is included.
Methods A and B are appropriate if the colour hue of the sample differs from the hue of the matching solution.
When stating the result, the procedure used (methods A to D) is also recorded.
